To all whom it may conoem:

Be it known that I, AXEL ULRIK Wnsrrnn'r, engineer, a subject of the King of Sweden, and a citizen of Sweden, residing at 43 Bergsgatan, Stockholm, in the Kingdom of Sweden, have invented new and useful Improvements in Sorting Apparatus for Coins, of which the following is a specifica- The present invention relates to a sorting apparatus for coins and the like, whichunlike other sorting apparatus hitherto knownis characterized especially thereby that ,the coins, having been fed inupon the apparatus fall down automatical y into their special compartments without any furtheractuat-ion of the coins, either directly or by shaking or moving of the apparatus being necessary. i

The invention is illustrated in the acshowing the present sorting device in plan view.-

The body of the ap aratus consists of an even and elongated p one or plate a and a box Z2 arranged below the plane or plate and divided into a certain number of compartments. The apparatus is arranged in such a manner that the plate a slopes both in the longitudinal and in the transversal direction of the plate, that is, the plate has its highest point-at the cornerc and its lowest point at the corner diagonally opposite the The coins are fed in upon the plate at or near the highest such a manner that one side against the plate a.

The coins are governed by means of lists or runways d, the edges of the coins running on the upper surface of said lists lying at right angles to the plane or plate a, This surface 18 hereinafter called the bearing surface. Along these lists or runways there are provided. a number cessively increasing in size downwardl in the same proportion as the diameter onl the diderent kinds of coins to be sorted.

The feed channel it is arranged at the upper end oil the plate a in such a position that the coins run in u on, the plate in a direction obliquely opposite to that in which the coins run down along the plate. Ihe coins are hereby caused to stop a moment and change direction of travel before running down along the runways, will always obtain the same speed in. runof the coins rest nmg down. From the feed channel it the point 0 and in .ture for the coins of the next size.

of apertures g suc-- so that they coins enter at the inside of a disk or the like 7', the lower edge of which closes tightly on the upper list or runway d serving to govern the coins' in proper position on the upper or first list (i. The apertures g for a certain size of coins is so broad that the distance between the bearing surface of the list and the up er edge of the aperture is greater than tile diameter of the coin in question," but shorter than the diameter of the coins of the next size. Further, as the apertures q increase in size downwardly and the coins owin to the plane being inclined both in thelongitudinal and in the will always engage the upper surface of the list (the bearing surface), it will be easily understood that a rolling coin will fall down just into the proper aperture. A coin of the second smallest size, for instance,

thus passes over the first apertur and falls down into the second aperture (taken from above,) etcetera. 0f course the coin-apertures 9 may not extend close to the list or runway g, but a part for supporting the coins is left between the apertures and the list. Preferably, however, a narrow slot e is provided in close proximity to the upper edge (bearing surface) of the list, for the purpose of preventing dust, dirt and the like mm collecting on the bearing surface of the list. Such collection of dust would cause a reduction of the exact distance between the bearing surface of the list and the upper edges of the apertures 01 cause a jumping movement of the coin, so that the coin would pass over the proper aperture 9 and fall down into the ape}:-

e box below the plate a: is, as mentioned, divided into compartments 7", one for each sort of coins. Between the disk or channel vided, one narrow and onebroadopening for each list or runway, and below these openings a special compartment 6 is prov1ded,'w'hich as well as the compartments 7'' y and the apertures g openings in are proprojects beyond the lower longitudinal edge of the plate a. Throughthese openings 7e such coins will tall down, which by any reason will be thrown into disorder and not run exactly against the runways, for instance, a coin which would obtain a gum ing movement or would abut against t e upper edge of another coin. Allsuch coins, which come out of order, thus will be collected into the compartment Z, wherefrom they may be taken out to be fed into the apparatus again. 'L

The walls of the compartment Z, at the lower end, project at a comparatively great distance above the plane a so as to catch coins, which eventually jump or roll over all the lists and openings k, The coins passing properly from the channel 7' run along the first list and fall down into their respective apertures g. The coins which immediately pass over the first list or runway are engaged by a spring obstructing member m and are thrown by this member against a shoulder a on the second listor runway and will thereby be governed into proper position on the said runway and fall down into the apertures adjacent thereto. lihe coins, which pass also over the second list are engaged by a second spring obstructing member '0, which throws the coins againsta shoulder 17 on the third list or runway and causes them to run down along 0f the coins and the transversal edges of sald apertures are oblique, in order to prevent the coins from passing over theirspecial apertures.

Having now particularly described and ascertained the nature of my said invention and in what manner'the same is to be per-v formed, I declare that what I claim is A sorting apparatus for coins comprising a plate having longitudinal and transverse inclination, a plurality of raised runways 7' formed with the plate and lying parallel to the longitudinal axis of said plate, means for introducing coins to the runways in a direction obliquely opposite to the 'longitudinal inclination of the plate, a series of coin apertures spaced apart, adjacent to said runways increasing in their respective sizes toward the lowest point of said runwa s and havin obli ue transverse'ed es.

a receiving hopper on said plate, openings through said plate between the hopper and graduated openings to deflect from the runways disordered coins, spring obstructing members disposed at right anglesto the upper ends of the runways between the hopper and said openings to guide the coins selectively into runways appropriate to their sizes, the bearing surfaces of the two upper runways being narrower than the thickness of the thinnest coin, to permit an overlying coin to slide over the underlying coin and pass to the next list, shoulders forming a continuation of the runways to' receive coins deflected by the spring obstructing members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
